Write the product using exponents.
2•2•2•n•n
As 2 and n is the factor and it is repeated three and two times respectively. So, exponent of 2 and n is 3 and 2 respectively.
2•2•2•n•n=23•n2
Hence, the product is 23•n2.
(-2)•(-2)•(-2)
3•3•3•y•y•y
Using laws of exponents, simplify and write the answer in exponential form:
(220÷215)×23
