The LCM of 10x and 45x^4 is 90x^4.
The LCM of 5, 18, and 45 would be 180 because: 5 times 36=180 18X10=180 and 45X4=180
453/4 x 473/8 = 45x4+3/4 x 47x8+3/8 = 183/4 x 379/8 = 183x379/4x8 = 69357/32 = 216713/32
i don't know what the problem is so um here are some examples i guessMULTIPLICATION5xX=20In this problem X=45x4=20SUBTRACTION80-X=43In this problem X=3780-37=43ADDITION5+X=98In this problem X=935+93=98Sorry i cant do the division example but i don't have a division signhope this will help youNinjainon123 out
