1

Understand the problem

(42)3+(g3)4= (4^2)^3+(g^3)^4=

2

Step-by-step solution

We use the formula:

(am)n=am×n (a^m)^n=a^{m\times n}

(42)3+(g3)4=42×3+g3×4=46+g12 (4^2)^3+(g^3)^4=4^{2\times3}+g^{3\times4}=4^6+g^{12}

3

Final Answer

46+g12 4^6+g^{12}

Key Points to Remember

Essential concepts to master this topic
  • Power Rule: When raising a power to a power, multiply exponents
  • Technique: (42)3=42×3=46 (4^2)^3 = 4^{2×3} = 4^6 and (g3)4=g3×4=g12 (g^3)^4 = g^{3×4} = g^{12}
  • Check: Verify exponents by counting: 42 4^2 cubed gives 46=4,096 4^6 = 4,096

Common Mistakes

Avoid these frequent errors
  • Adding exponents instead of multiplying
    Don't add exponents like (42)3=42+3=45 (4^2)^3 = 4^{2+3} = 4^5 = wrong answer! This confuses the power rule with the product rule. Always multiply exponents when raising a power to a power: (am)n=am×n (a^m)^n = a^{m×n} .

FAQ

Everything you need to know about this question

Why do I multiply the exponents instead of adding them?

+

When you have (42)3 (4^2)^3 , you're multiplying 42 4^2 by itself 3 times: 42×42×42 4^2 × 4^2 × 4^2 . Using the product rule, this becomes 42+2+2=46 4^{2+2+2} = 4^6 , which equals 42×3 4^{2×3} .

What's the difference between the product rule and power rule?

+

Product rule: am×an=am+n a^m × a^n = a^{m+n} (add exponents when multiplying same bases)

Power rule: (am)n=am×n (a^m)^n = a^{m×n} (multiply exponents when raising a power to a power)

How do I handle variables like g with exponents?

+

Variables follow the exact same rules as numbers! For (g3)4 (g^3)^4 , multiply the exponents: 3×4=12 3 × 4 = 12 , so the answer is g12 g^{12} .

Can I simplify 4⁶ to get a number?

+

You can calculate 46=4,096 4^6 = 4,096 , but usually it's better to leave it as 46 4^6 unless the problem specifically asks for the numerical value.

What if I have more than two levels of exponents?

+

Apply the power rule step by step! For example: ((x2)3)4=(x6)4=x24 ((x^2)^3)^4 = (x^6)^4 = x^{24} . Work from the inside out, multiplying exponents at each step.
