Answer:
2.5 × 10⁻⁹ × 1.5 × 10³ = 3.75 × 10⁻⁶
As you can see, you multiply the numbers in front of 10s, and add the exponents.
i think
Answer:
8x^2+14x^2+11x+2/4x+1
22x^2+11x+2/4x+1 ( It's 22x^2 cause 14x^2+*x^2 is 22x^2 and they are like terms.)
22x^2+11x+2/4x+1 ( The answer stays same cause there is no like terms so we can divide them)
The answer will be
1/64
