1.) Write 9.03 * 10^–2 in standard notation
The -2 means "move the decimal two to the left".
= 0.0903
---------------
2.)List the terms and coefficients. 8x^3 – 4x^2 + 3
Terms: 8x^3, -4x^2, +3
Coefficients: 8 ,-4, +3
==============
3.)Simplify. (m^5)^8
= m^40
==============
4.)Evaluate. 4^–5
The negative means "invert"
The 5 means "raise to the 5th power"
4^(-5) = (1/4^5 = 1/1024


=====================

1) 9.03*10^-2=1/903
2) 8X^3-4X^2+3=4X^2(2X-2)+3
3) (M^5)^8=M^40
4) 4^-5=1/4*4*4*4*4=1/1024
