G8 T1 Unit 1 Revision I (Simplifying Exponents)

Use exponents to write the expression p⋅p⋅r⋅r⋅r⋅r⋅n⋅n⋅n

Use exponents to write the expression (-7) ⋅ (-7) ⋅ 5 ⋅ 5 ⋅ 5 ⋅ 5

Use exponents to simplify the expression.
$$\frac{g\times g\times g\times f\times f}{g\times g\times f\times f\times f\times f\times f}$$

Evaluate the numerical expression $$3^4-\left(-4\right)^2$$

Evaluate the numerical expression. $$6+2^6$$

Evaluate $$x^3-y^2\ ,\ \ if\ \ x=2\ \ and\ \ y=\frac{3}{4}$$

Evaluate $$\left(g+h\right)^3$$ , if $$g=2$$ and $$h=-3$$

Put one of the symbols in the space between the numbers to make the expression true.

$$\left(-3\right)^4\$$ $$\left(-4\right)^3$$

A scientist estimated that, after a certain amount of time, there would be $$2^5\cdot3^3\cdot10^5$$ bacteria in a Petri dish. How many bacteria is this?

Simplify. $$3^8\cdot3$$
