Question

Write expression using a positive exponent

1. 5⁻ ²
2. -7 ⁻¹
3. t⁻⁶
4. n⁻²
write each expression as an expression using a negative exponent other than -1
5. 1/3⁴
6.1/9²
7.1/49
8.1/8

Answer 1

`1.\ \ 5^(-2)=(\frac15)^2=\frac1{5^2}\\\\ 2.\ \ -7^(-1)=-(\frac17)^1=-\frac1{7^1}\\\\ 3.\ \ t^(-6)=(\frac1t)^6=\frac1{t^6}\\\\ 4.\ \ n^(-2)=(\frac1n)^2=\frac1{n^2}\\\\\\ 5.\ \ (\frac13)^4=3^(-4)\\\\ 6.\ \ (\frac19)^2 =(\frac1{3^2})^2 =(3^(-2))^2=3^(-4)\\\\ 7.\ \ \frac1{49}=\frac1{7^2}=7^(-2)\\\\ 8.\ \ \frac1{8}=\frac1{2^3}=2^(-3)`
