Question

2i*-i -3*4 please find me this question​

Answer 1

Answer:

$\Large\boxed{-10}$

Step-by-step explanation:

GIVEN:

2i*-i-3*4

To solve this problem, first you have to use exponent rule formula from left to right numbers.

SOLUTIONS:

First, you have to remove parenthesis.

$\displaystyle 2i*-i-3*4$

$\displaystyle -2ii-3*4$

Use exponent rule formula.

$\Large\boxed{\textnormal{EXPONENT RULES FORMULA}}$

$\displaystyle A^B*A^C=A^B^+^C$

$\displaystyle i^1^+^1=ii$

$\displaystyle 2i^{1+1}$

Add.

$\displaystyle 1+1=2$

$\displaystyle 2i^2$

Multiply.

$\displaystyle 4*3=12$

Rewrite the problem down.

$\displaystyle -2i^2-12$

$\displaystyle 2i^2=i^2=-1$

$\displaystyle 2(-1)$

Remove parenthesis.

$\displaystyle -2*1$

Multiply the numbers from left to right.

$\displaystyle 2*1=2$

$\displaystyle -2$

$\displaystyle -(-2)-12$

Solve. (Simplify/ find the answer.)

Subtract.

$\displaystyle 2-12=\boxed{-10}$

$\Large\boxed{-10}$

So, the final answer is -10.
