Question 802378
y to the 8th power x y to the 3rd power = y squared
Assume the problem is
{{{y^8*y^3 = y^2}}}
y has to equal 1, but here is the procedure
When you multiply like terms, you add the exponents, so you have
{{{y^11 = y^2}}}
Divide both sides by y^2
{{{y^11/y^2}}} = 1
When you divide like terms, you subtract the dividing exponet
{{{y^9}}} = 1
Find the 9th root of both sides
y = {{{9sqrt(1)}}}
y = 1
