(-1/4-5/6+8/9)÷(-1/6)的2次方+(-2)的2次方ⅹ(-14)

(-1/4-5/6+8/9)÷(-1/6)的2次方+(-2)的2次方ⅹ(-14)

Answer 1

(-1/4-5/6+8/9)÷(-1/6)的2次方+(-2)的2次方ⅹ(-14)
=(-1/4-5/6+8/9)÷1/36+4ⅹ(-14)
=(-1/4-5/6+8/9)x36-56
=-1/4x36-5/6x36+8/9x36-56
=-9-30+32-56
=-63

Answer 2

(-1/4-5/6+8/9)÷(-1/6)^2+(-2)^2×(-14)
=（-9/36-20/36+32/36）÷1/36+4×（-14）
=1/12×36+（-56）
=3-56
=-53
