Dear HopellennibH, you need to FOIL. It is an algorithm to use when multiplying two binomials. Here are the steps. The "F" means to multiply the first two terms which gives you x squared. The "O" means to multiply the first term by the outer term, which gives you -8x. The "I" means to multiply the inner terms, which -9 times x which gives you -9x. The "L" means to multiply the last terms, which are -9 times -8, which gives you 72. Write the terms in standard form and you have x squared -17x +72.
Answer:
the correct option is option c.
Step-by-step explanation:
We have the expression: (160*243)^1/5
First, we know that 160 = 5(2^5)
And, 243 = 3^5
Then we have: (160*243)^1/5 = [5(2^5)(3^5)]^1/5 = 6(5)^1/5
So the correct option is option c.
We can write it down as a fraction:
and we can simplify this fraction:
=
=
=
or we can write it as a decimal:
0.1282...
