Indeterminate. How? a4b5 is the expression instead of equality. Since we are not given the equality of two variables, there is no way to determine whether it's invertible or not.

Otherwise, if you are referring "a" and "b" as invertible matrices, then yes it's invertible.

This all depends on the details.

Q: Is a to power of 4 multiplied by b to power of 5 invertible?

It is another name for index. A positive integer power of a number represents the number of occurrences of a number which are multiplied together. For example, 5^3 = 5*5*5.This definition gives rise to the power laws and these can be used to extend the definition of power to fractional and negative powers.It is often wrongly described as the number of time a number is multiplied by itself but this count does not work. But the 5^3 should be 5 multiplied by 5 three times = 5*(5*5*5) which actually is 5^4.

Two to the fourth power multiplied by five.

4 to the third power multiplied by 4 to the 5th power can be written as (4^3)x(4^5) When a number is raised to a power, it means that that number is multiplied by itself as many times as the power denotes. For example, 2 cubed, or 2^3, is two multiplied by itself three times. 2^3=2x2x2=8 In this case, (4^3)x(4^5)=(4x4x4)x(4x4x4x4x4) As you can see, this is the same as multiplying 4 by itself 8 times, or 4^8. At this point, the only way to know the answer is to multiply 4 by itself 8 times. 4x4x4x4x4x4x4x4=65,536 65,536 is your answer.
