00:07 Let's find out which expressions match the original one.
00:11 According to power laws, when you multiply powers with the same base, A,
00:16 you keep the base, and add the exponents, so it's A to the power of N plus M.
00:22 Let's use this formula in our exercise.
00:25 Here, we see addition, not multiplication, so this expression doesn't match.
00:31 This expression has multiplication, not addition, so it's not relevant either.
00:36 We'll keep the base, and add the exponents together for the correct solution.
00:43 And that's how we solve it!

1

Understand the problem

Expand the following equation:

4a+b+c= 4^{a+b+c}=

2

Step-by-step solution

To solve this problem, we will use the rule of exponents that allows us to expand the sum a+b+c a + b + c in the exponent:

  • Given: 4a+b+c 4^{a+b+c}
  • According to the exponent rule xm+n+p=xm×xn×xp x^{m+n+p} = x^m \times x^n \times x^p , we can express:
  • Step: Break down 4a+b+c 4^{a+b+c} to:
  • 4a×4b×4c 4^a \times 4^b \times 4^c

Therefore, the expanded form of the equation is 4a×4b×4c 4^a \times 4^b \times 4^c .

Final Answer

4a×4b×4c 4^a\times4^b\times4^c
