In x^7•x^4, how many x’s are multiplied together? (There’s 7 in the first factor and 4 in the second.)
x^7•x^4 = x^__? This is your a-value.
Similarly, y^2•y^5 = y^__? How many y’s are there in total being multiplied? This is your b-value.
762,872 that should be your answer if I’m correct
Answer:
875
Step-by-step explanation:
7*5^3=875
Answer:
for the first one y=2 if x=0 and for the second one I dont know
Step-by-step explanation:
We know <span>square of the sum <span>formula</span></span>
(a+b)²=a²+2ab+b²
so we need
x²+8x+c=(x²+2*4*x+4²)-16+c=(x+4)²+c-16,
so for full square we need c-16=0
c=16
Answer: c=16
