Question

( 1 2/3 *3 -(1 1/2)do potegi drugiej:4,5)=

( 1 2/3 *3 -(1 1/2)do potegi drugiej:4,5):2=

Answer 1

(1 2/3 * 3 - (1 1/2)^2 : 4,5) = (15/3 - 9/4 : 45/10) = 15/3 - 9/4 * 10/45 = 5 - 5/2 * 5/9 = 5 - 25/18 = 4 18/18 - 1 7/18 = 3 11/18

(1 2/3 * 3 - (1 1/2)^2 : 4,5) : 2 = 3 11/18 * 1/2 = 65/18 * 1/2 = 65/36 = 1 29/36

Answer 2

( 1 2/3 *3 -(1 1/2)do potegi drugiej:4,5)= 5/3*3/1 -(3/2) do potęgi 2 :4,5 = 15/3 -9/4 :4,5=
9/2=4,5

( 1 2/3 *3 -(1 1/2)do potegi drugiej:4,5):2=5/3 *3/1 -(3/2) do potęgi 2 :4,5) :2=15/3 -9/4 :4,5 ):2 =2.25
