What is the exponent for the factor of 3 in the expression \( 3 b^{4} \) ? The exponent that corresponds to the factor of 3 is

The exponent that corresponds to the factor of 3 in the expression \( 3 b^4 \) is 1, since 3 can be expressed as \( 3^1 \). Any number without an explicit exponent can be assumed to have an exponent of 1. So, in this case, you're just looking at the base, which is 3, and since it’s the only factor present alongside \( b^4 \), its exponent is indeed 1.
