Q. 8−21⋅867What is the value of the given expression?
Apply exponent property: Apply the property of exponents that states when multiplying expressions with the same base, you add the exponents.8−(21)×867=8(−(21)+67)
Add exponents: Add the exponents (−21) and 67 together.(−21)+67=(−63)+67=64
Simplify the fraction: Simplify the fraction(4)/(6) by dividing both the numerator and the denominator by their greatest common divisor, which is 2.(4)/(6)=(2×2)/(2×3)=(2)/(3)
Substitute simplified exponent: Substitute the simplified exponent back into the base 8. 8(4)/(6) simplifies to 8(2)/(3)
Calculate value of 832: Calculate the value of 8(32). Since 8=23, we can rewrite 8(32) as (23)(32).(23)(32)=23(32)=22
Calculate value of 22: Calculate the value of 22.22=2×2=4
