(x3)(x4) is x7 because when you have a problem like that, you have to ADD your exponents.
-(m4)3 is -m12 since you're multiplying them.
(z3)5 is z15
y4 x y5 is y9
thats all i know of. hope it helps cx
Answer:
Yes.
Step-by-step explanation:
According to medical science, a body temperature considered normal (that is, below fever) in degrees Fahrenheit is 98ºF, while its equivalent in degrees Celsius is 36.6ºC. Therefore, a body temperature of 39ºC is higher than 98ºF, being equivalent to 102.2ºF.
This is verified by applying the conversion formula from Celcius to Fahrenheit:
(39 x 9/5) + 32 = X
39 x 1.8 + 32 = X
70.2 + 32 = X
102.2 = X
A, B and D are already rational numbers, 0.4 itself is a rational number, two rational numbers make a product of rational number.
So A, B, D are the correct choices.
Are you sure it asks for rational numbers, not irrational number?
It is right, because 36 is dividable by 6 and 9 (haha thats the funny number)
When you are finding 2 consecutive numbers that a square root falls between, you have to think about what the closest whole numbers are, for example, if you have the sq root of 17, it would fall between 4² (16) and 5² (25).
So, in this case, √105 would fall between 10² (100) and 11² (121)
