### Relevant Questions in number 7, Is the exponent of (-1) n right? I thought that the exponent of (-1) is n-1 because it changed from n=0 to n=1, and if $$(-1)^{n}$$, there will be a change of sign between negative sign and positive sign. Deduce from the Completeness Axiom that there exists a square root of a real number a if and only if a ≥ 0 The central processing unit (CPU) power in computers has increased significantly over the years. The CPU power in Macintosh computers has grown exponentially from 8 MHz in 1984 to 3400 MHz in 2013 (Source: Apple. The exponential function $$\displaystyle\{M}{\left({t}\right)}={7.91477}{\left({1.26698}\right)}^{{t}}{\left[{m}{a}{t}{h}\right]}$$, where t is the number of years after 1984, an be used to estimate the CPU power in a Macintosh computer in a given year. Find the CPU power of a Macintosh Performa 5320CD in 1995 and of an iMac G6 in 2009. Round to the nearest one MHz. Simplify: $$\displaystyle{\left({7}^{{5}}\right)}{\left({4}^{{5}}\right)}$$. Write your answer using an exponent.
Explain in words how to simplify: $$\displaystyle{\left({153}^{{2}}\right)}^{{7}}.$$
Is the statement $$\displaystyle{\left({10}^{{5}}\right)}{\left({4}^{{5}}\right)}={14}^{{5}}$$ true? Simplify sqrt-54 using the imaginary number i

Write answers without negative exponnents. $$\displaystyle{\left({4}{x}^{{2}}{y}^{{-{{3}}}}\right)}^{{-{{2}}}}$$ Write each radical expression using exponents and each exponential expression using radicals. Radical expression Exponential expression $$\sqrt{y^{4}}$$  If $$\displaystyle{s}≥{0}$$, then $$\displaystyle√{s}^{{2}}$$ is equal to
