Solve the expression 15x8^0+4(7^0-6)

15x8^0+4(7^0-6)=

15x8^0+4(7^0-6)

= 15x1+4(1-6)
= 15+4(-5)
= 15-20
= -5

To solve the expression 15x8^0+4(7^0-6), we can start by simplifying the exponents:

Any number raised to the power of 0 is equal to 1. So, 8^0 = 1 and 7^0 = 1.

Now we substitute these values back into the expression:

15x(1) + 4(1 - 6)

Next, we simplify the multiplication:

15 + 4(1 - 6)

Now we simplify the subtraction inside the parentheses:

15 + 4(-5)

Finally, we perform the multiplication:

15 + (-20)

The final step is to add the two numbers:

15 - 20 = -5

Therefore, the solution to the expression 15x8^0+4(7^0-6) is -5.
