@Bobo-i-bo
what is (x^b)^c = ? (formula you have to remember)
um i dont know
it is : \((x^b)^c = x^{bc}\).
oh okk
and \(x^a \times x^b = x^{a+b}\). What is the answer then?
x^ab?
I mean, answer to your original quesiton. (the horses)
oh 4^6
right
Which number is not in scientific notation? 0.95 ⋅ 10^8 1.1 ⋅ 10^5 7.00 ⋅ 10^8 9.9 ⋅ 10^−28
@reemii a?
Correct
Which expression is rational? 6.27316543222718… square root of 2 square root of 14. square root of 49
Because for it to be in scientific notation the number before 10^x has to be between 1 and 10, and 0.95 is less than 1
Rational means that the number ends. You can see if it ends by putting it into the calculator.
D?
yes
Which of the following numbers is irrational? a fraction with numerator negative 15 and denominator 4, a fraction with numerator negative 7 and denominator 9, square root of 4, π a fraction with numerator negative 15 and denominator 4 a fraction with numerator negative 7 and denominator 9 square root of 4 π
I will tell you that π is an irrational number because it goes on without repeating.
@reemii is that correct? d?
@jim_thompson5910
Yes d is correct. -7/9 is rational because its decimal form is predictable. It's -7.9999999 repeating and the nines go on predictably.
