What is (e^x) squared?Question:What is (e^x) squared?ExponentsAn exponent is a power to which a number is raised and is mathematically represented as {eq}a^x {/eq} where {eq}x {/eq} is the exponent. This means that {eq}a {/eq} is multiplied by itself {eq}x {/eq} times....
The square root of a given number is the positive number (or zero) so that when squared results in that given number . That is it. So, given a number xx, its square root is a number bb so that b≥0b≥0 and b2=xb2=x By looking at the above expression, we can see that if ...
