Answer 2

SOLUTION

TO DETERMINE

The value of

$\sf {x}^{7} \times {x}^{2}$

EVALUATION

We are aware of the formula on indices that

$\sf {a}^{m} \times {a}^{n} = {a}^{m + n}$

Here the given expression is

$\sf {x}^{7} \times {x}^{2}$

We now use the formula

$\boxed{ \: \: \sf {a}^{m} \times {a}^{n} = {a}^{m + n} \: \: }$

Thus we get

$\sf {x}^{7} \times {x}^{2}$

$\sf = {x}^{7 + 2}$

$\sf = {x}^{9}$
