Simplify the following equation:

62×65×6= 6^2\times6^5\times6=

Step-by-step solution

To simplify the expression 62×65×6 6^2 \times 6^5 \times 6 , we apply the rules of exponents because all terms have the same base.

  • Identify each power: 62 6^2 , 65 6^5 , and 6 6 . Remember that 6 6 is equivalent to 61 6^1 .

  • Using the exponent multiplication rule: am×an=am+n a^m \times a^n = a^{m+n} .

  • Combine the exponents: 62+5+1 6^{2+5+1} .

  • Calculate the sum of the exponents: 2+5+1=8 2 + 5 + 1 = 8 .

Therefore, the solution to the problem is 68\boxed{6^8}.

Final Answer

68 6^8

Key Points to Remember

Essential concepts to master this topic
  • Rule: When multiplying powers with same base, add the exponents
  • Technique: Write 6 as 61 6^1 , then add: 2+5+1=8
  • Check: Count total factors: 6×6×6×6×6×6×6×6 = 68 6^8

Common Mistakes

Avoid these frequent errors
  • Multiplying the exponents instead of adding them
    Don't calculate 62×5×1=610 6^{2×5×1} = 6^{10} = wrong answer! This confuses the multiplication rule with the power rule. Always add exponents when multiplying powers with the same base: 62+5+1=68 6^{2+5+1} = 6^8 .

FAQ

Everything you need to know about this question

Why is 6 the same as 61 6^1 ?

+

Any number without a visible exponent has an implied exponent of 1. Just like 6 = 6¹, because 6 appears once as a factor. This is why 62×65×6 6^2 × 6^5 × 6 becomes 62+5+1 6^{2+5+1} .

What if the bases were different numbers?

+

You cannot combine exponents when bases are different! For example, 52×63 5^2 × 6^3 stays as is. The exponent addition rule only works when all bases are identical.

How do I remember when to add vs multiply exponents?

+

Multiplying powers: add exponents (am×an=am+n a^m × a^n = a^{m+n} )
Power of a power: multiply exponents ((am)n=am×n (a^m)^n = a^{m×n} )
Look for × between terms vs parentheses around powers!

Can I just calculate 62×65×6 6^2 × 6^5 × 6 without using exponent rules?

+

You could calculate 36×7776×6 36 × 7776 × 6 , but that's much harder! Using exponent rules keeps numbers manageable and shows mathematical understanding. The answer 68 6^8 is cleaner than 1,679,616.

What does 68 6^8 actually equal?

+

68=1,679,616 6^8 = 1,679,616 . But in most problems, leaving the answer as 68 6^8 is preferred because it's simplified form and shows the pattern clearly.
