Question

I will give Brainliest its maths and I need help on a b and c

Answer 1

Answer:

${5}^{3} \times {5}^{x} = {5}^{7} \\ 3 + x = 7 \\ x = 4$

$( {q}^{2} )^{y} = {q}^{6} \\ 2y = 6 \\ y = 3$

${1000}^{m} \div {100}^{n} = {10}^{z} \\ \frac{1000 ^{m} }{ {100}^{n} } = {10}^{z} \\ \\ {10}^{m - n} = {10}^{z}$

Can I have the brainliest please?
