Answer 2

Given,

• $5a^{25} -3a^{32} + 2a^{-12}$ is given.
• a = 1

To find,

• We have to find the value of $5a^{25} -3a^{32} + 2a^{-12}$ if $a=1$.

Solution,

The value of $5a^{25} -3a^{32} + 2a^{-12}$ for $a=1$ is 4.

We can simply find the value of $5a^{25} -3a^{32} + 2a^{-12}$ if $a=1$ by substituting the value of a = 1 in the given expression.

                       $p(a) = 5a^{25} -3a^{32} +2a^{-12}$

                       $p(1) = 5(1)^{25} -3(1)^{32} +2(1)^{-12}$     [$a^{-m} = 1/a^m$]

                               = $5-3 +2/(1)^{12}$

                               = $5-3+2$

                               = $4$

∴ Value of $5a^{25} -3a^{32} + 2a^{-12}$ for $a=1$ is 4.

Hence, the value of $5a^{25} -3a^{32} + 2a^{-12}$ for $a=1$ is 4.
