To obtain 58 percent of 18 multiply 18 by 0.58, because 58 percent is equal to 58/100. That said, your result rounded to two decimals is 10.44.
This answers what is 58% of 18. If you have a currency, such as in the case of 18 dollars, proceed as outlined in the example right below.
Answer: 17.9
Step-by-step explanation:
We want to multiply the monomial
by the monomial
.
Remember that to multiply monomials we need to use the laws of exponents; in this case, the law for multiplying powers with the same base. The rule says that, when you multiply powers of the same base, you just need to add the exponents:
,
. Also, is worth pointing out that the exponent of a variable with no exponent is 1:
.
Remember that we also need to multiply their coefficients , which are the numbers that multiply the variables; again, variables with no numbers have a coefficient of 1, so
. Multiply coefficients is easy, you just need to multiply them as you usually do with everyday numbers.
Let's apply all of that to our multiplication:
![(2x)(x^2)=(2x^1)(1x^2)=2*1x^{1+2}=2x^3](https://tex.z-dn.net/?f=%20%282x%29%28x%5E2%29%3D%282x%5E1%29%281x%5E2%29%3D2%2A1x%5E%7B1%2B2%7D%3D2x%5E3%20)
We can conclude that 2x times x squared is 2x cubed.
