Question

Choose the incorrect option :

• A. $4^1=1$
• B. $0^4=0$
• C. $1^4=1$
• D. $4^1=4$

Answer 1

The correct option is A $4^1=1$

For the base of 4 and exponent of 1, the value can be written as :
$4^1=4\times 1=4$
Hence, $4^1=4$

when base is zero and the value of exponents is 4.
$0^4=0\times 0\times 0\times 0=0$
Hence, $0^4=0$

When the base is 1 and exponent is 4, the value can be written as :
$1^4=1\times 1\times 1\times 1$
Hence, $1^4=1$

When the base is 4 and exponent is 1, the value can be written as :
$4^1=4$
Hence, $4^1=4$
Option a is incorrect.
