Question

Identify the incorrect step in solving the expression

Answer 1

Answer: step 2, instead of adding the exponets together they should have done 5^3 first and then done the result of that (125) ^2

Answer 2

When you multiply an exponent directly into another exponent, you multiply the exponents.

For example:

$(x^{2} )^6=x^{2(6)}=x^{12}$

$(x^{4})^1=x^{4(1)}=x^4$

$(5^{3})^2=5^{3(2)}=5^6$

So #2 is incorrect
