`a, = x^(7+4+1) = x^12`
`b, = (3.4)^5 = 12^5`
`c, = 2^15 . 2^3 = 2^18`
a: \(=x^{7+1+4}=x^{12}\)
b: \(=12^5\)
c: \(=2^{15}\cdot2^3=2^{18}\)
\(x^7.x.x^4=x^{7+1+4}=x^{12}\)
\(3^5.4^5=\left(3.4\right)^5=12^5\)
\(8^5.2^3=\left(2^3\right)^5.2^3=2^{15}.2^3=2^{18}\)
`x^7 . x . x^4 = x^(7+1+4) = x^12`
`3^5 . 4^5 = (3.4)^5 = 12^5`
\(8^5.2^3=2^{3^5}.2^3=2^{3.5}.2^3=2^{15}.2^3=2^{15+3}=2^{18}\)
a) \(=x^{7+4+1}=x^{12}\)
b) \(=\left(3.5\right)^5=12^5\)
