Question

$5 {}^{2} \times 5 {}^{7} \times 5 {}^{12}$
Simplify and write in exponential form.​

Answer 1

Answer:

${5}^{21}$

Step-by-step explanation:

We know that,

${a}^{m} \times {a}^{n}$

=

${a}^{m + n}$

So,

$5 {}^{2} \times 5 {}^{7} \times 5 {}^{12}$

=

${5}^{2 + 7 + 12}$

=

${5}^{21}$
