Question

Help me with this math problem please

Answer 1

The answer is 4 to the power of 0

Answer 2

The expression
${4}^{5} \times {4}^{ - 7} \div {4}^{ - 2}$
is the same as
$\frac{ {4}^{5} \times {4}^{ - 7} }{ {4}^{ - 2} }$
Which, if we switch the negative exponents, equals
$\frac{ {4}^{5} \times {4}^{2} }{ {4}^{7} }$
And if we combine them, they equal
$\frac{ {4}^{7} }{ {4}^{7} }$
Then we divide, and they equal
${4}^{0}$
