9- Indicate and carry out the corresponding enhancements: a) base - 8 and exponent 3; b)-2 raised to the fourth power; c)+30 squared; d) base 0 and exponent 100, e)+9 cubed;

Respuesta :

a) Exponential expressions have the next form:

[tex]b^x[/tex]

where b is the base and x is the exponent. Substituting with b = -8 and x = 3, we get:

[tex](-8)^3=-512[/tex]

b) In this case, the base is -2 and the exponent is 4:

[tex](-2)^4=16[/tex]

c) In this case, the base is 30 and the exponent is 2:

[tex]30^2=900[/tex]

d) In this case, the base is 0 and the exponent is 100:

[tex]0^{100}=0[/tex]

Note that when the base is zero, the value of the expression is also zero.

e) In this case, the base is 9 and the exponent is 3:

[tex]9^3=729[/tex]
