Question

simplify using exponential law: (27*125*63)/(49*81*75)

Answer 1

Answer:

0

Step-by-step explanation:

=(27*125*63)/(49*81*75)

={3*3*3*5*5*5*7*3*3}/{7*7*3*3*3*3*15*5}

={3*3*3*5*5*5*7*3*3}/{7*7*3*3*3*3*3*5*5}

={3^5*5^3*7}/{7^2*3^5*5^2}       ^x is the power of the last number

=3^5-5*5^3-2*7^1-2

=3^0*5^1*7^-1

=0*5*(1/7)

=0
