Question

U=5⁷×5-³ and v=10¹⁰÷10⁶ so what is the value of v and u

Answer 1

$u = {5}^{7} \times {5}^{ - 3}$

$u = {5}^{(7 - 3)}$

$u = {5}^{4}$

$u = 5 \times 5 \times 5 \times 5$

$u = 625$

$v = {10}^{10} \div {10}^{6}$

$v = {10}^{10 - 6}$

$v = {10}^{4}$

$v = 10 \times 10 \times 10 \times 10$

$v = 10000$
