Simplify the expression if possible 4^3 × 4^5 and write you answer as a power ( using exponents )
alexgriva [62]

Answer:

4^8

Step-by-step explanation:

If you are multiplying two bases that are the same with different exponents, the exponents get added and the base stays the same:

x^a*x^b=x^{a+b}\\\\4^3*4^5=4^{3+5}\\\\4^3*4^5=4^8

Therefore, 4^3 * 4^5 = 4^8

Y=x+3 <br> 2x-y=-1<br> write solution as ordered pair
dsp73

The first equation tells you that y=x+3. If you substitute this expression for y in the second, we have

2x-(x+3)=-1 \iff x-3=-1 \iff x=2

And we can deduce y=x+3=2+3=5
